ELORZA D, JAVIER; ROSSAT A, CRISTIAN  y  ORELLANA E, OSCAR. Right thyroid hemiagenesis and microcarcinoma of the left lobe: Report of one case. Rev Chil Cir [online]. 2010, vol.62, n.3, pp. 268-271. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262010000300011.

In congenital thyroid hemiagenesis, one of the thyroid lobes, usually the left one, does not develop. This condition is generally asymptomatic. We report a 47 years old female with a diffuse left goiter. An ultrasound detected the right lobe hemiagenesis. She was subjected to a subtotal thyroidectomy. The pathological study of the surgical piece disclosed the presence of an encapsulated papillary carcinoma, follicular variant with a diameter of 2 mm.
